Definitions
- the present invention relates to a display window of a mobile phone, and more particularly to an improved construction of a display window, which is provided at a mobile phone so as to protect a liquid crystal screen of the mobile phone, on which various information is displayed.
- Mobile phones have various shapes and functions for providing convenience for users of the mobile phones.
- a liquid crystal screen displaying general information about the mobile phone for users is disposed at a central portion of the mobile phone.
- the liquid crystal screen displays various information required in using the mobile phone, such as the phone number and transmission/reception state.
- the mobile phone is often and widely utilized in transmitting E-mails, character messages, etc., so that the dimension of the liquid crystal screen has a tendency to be increased.
- a display window 1 made from synthetic resin is assembled outside of the liquid crystal screen as illustrated in FIG. 1 .
- a deposited layer 11 is first formed on a flat transparent sheet 10 made from synthetic resin though a deposition step, in which nonferrous metal powder such as powder of Al, Ni, Cu, or Ti is deposited and coated on the flat transparent sheet. Thereafter, a printed layer 12 having various rim shapes such as a rectangular-rimmed shape is formed on the deposited layer 11 .
- an etching is performed by utilizing predetermined chemicals, to eliminate predetermined portions of the deposited layer 11 , thereby changing opaque portions of the display window 1 covered by the deposited layer 11 into transparent portions, through which the liquid crystal screen can be viewed.
- an etched sheet 13 is manufactured by the etching, various characters required by manufacturers of mobile phones, such as symbols and logos of the manufacturers, are printed on the printed layer 12 , and the etched sheet 13 is cut along the shape of the remaining deposited layer 11 , so that complete display windows 1 for mobile phones are manufactured.
- an object of the present invention is to provide a display window of a mobile phone, in which a protective layer is formed along an edge of the display window, so as to prevent a deposited layer from being exposed and being oxidized/corroded, thereby improving not only the quality of the display window but also the reliability on the mobile phone provided with the display window.
- a display window for protecting a liquid crystal screen of a mobile phone comprising: a transparent sheet made from synthetic resin and having a predetermined thickness and area; a deposited layer formed on the transparent sheet; a printed layer formed on the deposited layer and having a shape of a closed loop with a regular width, the printed layer having an outer edge disposed a predetermined space inside from an outer edge of the transparent sheet; and a protective layer formed in the predetermined space between the outer edge of the transparent sheet and the outer edge of the deposited layer, the protective layer being transparent or colored.
- the deposited layer is formed by etching after depositing nonferrous metal powder on an entire surface of the transparent sheet, so that the deposited layer remains only between the printed layer and the transparent sheet, and the protective layer is coated on outer edges of the deposited layer and printed layers, thereby preventing the deposited layer from being exposed.
- FIG. 1 is a perspective view of a conventional mobile phone
- FIG. 2 is a view illustrated a process of manufacturing a conventional display window of a mobile phone
- FIG. 3 is a plan and a side view of a conventional display window of a mobile phone
- FIG. 4 is a view illustrated a process of manufacturing a display window of a mobile phone according to a preferred embodiment of the present invention.
- FIG. 5 is a plan and side view of a display window of a mobile phone according to a preferred embodiment of the present invention.
- a display window of a mobile phone according to the present invention includes a central portion, a transparent portion formed at peripheral portions of the window, and an opaque section in which a deposited layer and a printed layer overlap each other.
- a display window 2 of a mobile phone according to the present invention includes a transparent sheet 20 having a predetermined thickness and area made from synthetic resin, and a deposited layer 21 deposited on the entire surface of the transparent sheet 20 .
- the deposited layer 21 has a uniform thickness and is formed by depositing nonferrous metal powder on the transparent sheet 20 .
- a printed layer 22 is formed on the deposited layer 21 in such a manner that the printed layer 22 has a predetermined width b so as to form the external appearance of the display window 2 corresponding to the liquid crystal screen of the mobile phone.
- the outer edge of the printed layer 22 is not equal to that of the conventional display window, but is disposed a predetermined distance inside from the outer edge of the display window 2 when the display window 2 is completed, as illustrated in FIG. 5 .
- the transparent sheet 20 is subjected to an etching by means of predetermined chemicals, so as to eliminate predetermined portions of the deposited layer 21 , thereby changing opaque portions of the surface of the transparent sheet 20 covered by the deposited layer 21 into transparent portions, through which the liquid crystal screen can be viewed.
- a transparent film or film with one of various colors is coated on an etched portion 24 , which means exposed outer edges of the deposited layer 21 and the printed layer 22 .
- the transparent sheet 20 is cut not along the outer edge of the printed layer 22 but along a portion including the coated film outside of the outer edge of the printed layer 22 , so that the coated film forms a protective layer 26 having a predetermined width along the rim of the display window 2 as illustrated in FIG. 5 .
- the deposited layer 21 is not exposed but is covered by the protective layer 26 , that is, the coated film. Therefore, the protective layer 26 prevents the deposited layer 21 from being oxidized/corroded, differently from the conventional display window, in which the deposited layer 11 and the printed layer 12 are exposed and the deposited layer 11 is oxidized/corroded.
- the printed layer 22 has a smaller width in comparison with that of the prior art, while the entire width of the transparent section is maintained the same, and the protective layer 26 is formed in the gap formed due to the difference of the width, so that there is no change in the entire dimension of the display window.
- a protective layer formed along the edge of the display window prevents the deposited layer from being exposed and being oxidized/corroded, thereby improving not only the quality of the display window but also the reliability of the mobile phone provided with the display window.
